COIN-TESTER.

oeaeae.

To all whom it may concern:

Be it known that I, LAnIsLAw PACIOR- ninwioz, a citizen of the German Empire, and residing at Charlottenburg, Germany, have invented certain new and useful Improvements in Coin-Testers, of which the following is a specification.

My invention relates to coin-testers, and a primary object is to provide an improved coin-tester by which the inserted coin is tested as to whether it is provided with a predetermined impression. To this end, I

v arrange that as soon as the coin has been inserted into the inlet it passes between two feelers or pointers which are adjusted in such manner that a smooth disk passes between them and falls into the outlet channel, while a properly impressed coin tem porarily remains between the feelers as soon as the latter are located against a raised inscription or impression, whereupon it is released, owing to the locking mechanism being unlocked for example, and is conducted to the channel leading to the till. According to the nature of the impression or inscription in each instance the coin is stopped at higher or lower place, so that only those coins having a predetermined inscription or impression are stopped in the correct posi tion in which, after the coin has been released, the outlet channel can be closed and the channel leading to the till opened. The release of the unlocking device and the closure of the outlet channel are preferably effected by the coin itself when the same passes through the testing device without being stopped and impacts against an elastic stop; the latter causes the outlet to be opened and simultaneously gently throws the coin back bet-ween the testing feelers or brushes, where it temporarily remains stuck in the correct position. In another form of my invention the coin is positively driven forward against the action of the elastic stop by the blow of a lever.

Two illustrative embodiments of my invention are represented by way of example in the accompanying drawings, wherein Figure 1 is a front elevation showing one form of my improved coin-tester, and Fig. 2 is a side elevation thereof; Fig. 3 is a side elevation showing another form; Figs. 41- and 5 are end elevation, and top plan View,

respectively, showing the right-hand part of the mechanism shown in Fig. 3. 7

Referring firstly to Figs. 1 and 2, the channel 1 comprises a slanting portion from which too small coins are ejected, and a lower vertical portion in which the inscripthe channel 1 it strikes against the pin 8 of a lever 9, rocks the latter upward and releases the lever 10; this lever 10 is rotatable about the pivot 1.1 and, owing to the weight 12, tends to rock clockwise as seen in Fig. 2. This lever 10 consequently rocks to the right and withdraws its projection 13 so far that the lug 1 1 of the lever 6 is released. Further, when the lever 9 rocks, its arm 15 presses against the curved arm 16 mounted on the lever 6 and rocks the latter. This arm 16 is mounted to rock about the screw 17 on the lever 6, but is so connected by a spring 18 of sutlicient tension with the lever 6 that it rocks thereon only when the lever 6 meets with a specially great resistance when rotating. In this manner injuries to the mechanism are prevented when a disturbance occurs, 6. g. owing to a coin becoming stuck. As soon as the lever 6 has rotated a predetermined distance the member 19 carried by a spring 20 mounted on the lever 6 snaps into a recess in the locking member 21 carried by the channel 1, whereby the lever 6 which, owing to the spring 22, tends to return into its normal position, is temporarily locked in its working position. The lever 9, which is likewise influenced by a spring 29, tends to return into its normal position as soon as the coin has passed under the pin 8, but is temporarily prevented therefrom because its end 23 bears on the end 30 of the lever 6. The coin now falls down the vertical portion of the channel 1 and arrives between the points of the elastic feelers or pointers 24:. It impacts on the spring 20, so that this spring is pressed downward and the member 19 is removed from the recess in the locking member 21.

The lever 6 is therefore released and returns into its normal position, the spring 20 being removed out of the incision in the channel. The lever 9 is simultaneously released and falls on the lever 10 which likewise returns into its normal position. As soon as the coin falls onto the spring 20 it flies back again owing to the elasticity of the spring. In order to regulate the recoil of the spring 20 a set-screw 25 is provided. The coin moves upward, but as the springs 24, which preferably have sharp, spoon-shaped ends, are located at an acute angle relatively to the coin, when the latter is provided with a sharp impresion or inscription it very soon remains stationary between the feelers, whereas smooth disks and similar pieces fly back materially farther. The position and shape of the feelers must, of course, be adapted to the character of the coin, in order to differentiate between various kinds of coins. For example, German small coins have on the one side a raised inscription such as Deutsches Reich 190T Pfennig forming a complete circle. Such a coin arrives without difficulty between the two feelers, but as soon as it returns upward, the one or the other feeler according to the side of the coin on which the numeral designating the value of the coin is provided abuts against the inscription and stops the coin. When the coin has been stopped in the correct position, the lever 6 can rock without resistance opposing it, and the member 4; blocks the branch channel 3, so that the coin falls through the branch channel 2 into the till. If the coin or a counterfeit coin has flown upward too high, on the contrary, the projection 26 of the lever 6 projecting through an aperture provided in the channel 1 abuts against the coin, whereby the return movement of the lever 6 is delayed until the lever 10 has returned into its normal position and the projection 13 is located in front of the lug 14-. of the lever 6. In this position of the lever 6 the member 1 releases the branch channel 3 through which the counterfeit coin falls. The lever 10 has two lugs 27 which press against the feelers 24, whereby after the return of the lever 10 into its normal position, the feelers are spread apart and the temporarily held coin is released. The loop 28 is for guiding the lever 9 in its elevated position.

Referring now to Figs. 3, t and 5, the slanting channel 1 having the till outlet 2 and the repayment outlet 3 has mounted on its side a lever 9 rotatable about the screw 29. A pin 8 on this lever projects through an aperture in the wall of the channel 1 into the channel, so that when a coin is inserted into the inlet 7 the lever 9 is rocked upward. Attached to the lever 9 is an airbrake 31 for retarding the movements of this lever. At the right-hand end of the channel 1 is the spring-pressed lever l which is mounted to rock about the pivot 5 and in its normal position, in which it is held by its spring 32, blocks the outlet 3' of the channel 1. As clearly shown in Fig. 4, this lever embraces the channel 1 on both sides and carries on the right-hand side the elastic stop 20. The pivot 5 also carries a lever 33 which is beveled below and normally projects through an aperture in the wall of the channel 1 into the path of the coins. This lever 33 is rigidly connected with the lever 4 and constitutes an arm thereof. The lever 10 is mounted to rock about the pivot 11, carries the weight 12 and holds apart the elastic feelers 2% by means of the projections 27' on the two sides of the channel 1. The lefthand arm of this lever is normally pressed down by a pin 34: provided 011 the lever 9 and the weight 12 is lifted. In this position the lever 10 enters into one of the two recesses 35, 36 in the lever 33 and locks the latter. As soon as the lever 9' is rocked upward owing to the insertion of a coin, in consequence of the weight 12 the lever 10 rocks clockwise and releases the feelers 24' and the lever 33. The shoulder 37 of the lever 9 bears against the slanting face of the lever 33 and rocks this lever clockwise, as seen in Fig. t. The opening 38 in the channel 1 is simultaneously closed by the lug 39 of the lever 9. The hook 1O at the extreme end of the lever 9 slides in the meantime along the elastic stop 20 and becomes hooked on the top end thereof, so that the lever remains suspended in this position. As soon as the coin strikes against the elastic stop 20 the top end thereof is pushed backward and the hook 40 of the lever 9 is released. The projection all of the lever 9 which projects through a slot into the channel 1, now slides along the back of the coin and positively presses the coin a predetermined distance in the direction of the stop 20 which yields correspondingly. As soon as the projection 41 has passed along the coin the spring 20 presses the coin back again and the points of the feelers 24 pass over the surface of the coin and hold the same as soon as one of these feelers bears against an impression or inscription. The shoulder 37 has released the lever 33 in the meantime, so that the latter flies back under the action of the spring 32 into its normal position. The inner point of the lever 33 now projects into the channel 1 and passes by the coin when the coin has been stopped at the right place by the feelers 24. In this event the lever 33 can return into its normal position. In this position the lever 1 blocks the outlet 3 of the channel 1. The pin 34 arrives finally on the lever 10 and rocks it so that the projections 27 spread the feelers 24 apart; the coin is released and passes through the outlet 2 into the till. In case the coin is not stopped in the correct position by the feelers 24, when the lever 9 is released from the spring 20 and releases the lever 33 the point of the lever 33 abuts against the coin, whereby this lever 33 is duly stopped. The opening 3' is not closed, and the lever 10 falls into the recess 36 in the lever 33. When the coin is now released owing to the feelers being bent apart, it passes out through the outlet 3 and is returned along a repayment channel. The position of the coin can, of course, be checked by several projections distributed at suitable places at the periphery of the coin in its correct position. For testing 50-pfennig pieces such feelers may be so arranged that they feel over the milled edge of the coin. lVhen the coin is too small the lever 9 is not rocked upward far enough when the coin is inserted, so that the hook 40 does not become hooked on the end of the stop 20. The lever is only partially lifted and falls back at once when the coin has passed under the pin 8. The coin then falls through the opening 38 and is rejected.
